Cladding

Cladding is the process of depositing a material on the surface of another for enhanced material properties (primarily corrosion resistance). While C&J specializes in GTAW-P-HW cladding, we also perform cladding using most other welding processes. The most common material for Oil & Gas cladding is nickel alloy 625, but with developing technology and advancements in material properties we are discovering new alloys that may result in longer life for your project.

There are 180 welding procedures developed for cladding.

Processes

  • GTAW-P-HW (Gas Tungsten Arc Welding Pulsed Hot Wire)
  • GTAW (Gas Tungsten Arc Welding or TIG or Heli-Arc)
  • SAW (Submerged Arc Welding)
  • SMAW (Shielded Metal Arc Welding or STICK)
  • GMAW (Gas Metal Arc Welding)
  • PAW (Plasma Arc Welding)
  • PTAW (Plasma Transferred Arc Welding) Wire Feed
  • PTAW (Plasma Transferred Arc Welding) Powder Feed
  • Above processes utilize manual, semi-automatic, and mechanized systems
